Description
I request the three member functions
template< class U > bool boost::optional<T>::optional_assign_to(U& t) const; template< class U > bool boost::optional<T>::optional_move_to(U& t); bool boost::optional<T>::optional_swap(T& t);
which, if !*this, return false, and otherwise return true and are equivalent to
t=this; t=this; and *this may have any value after the move std::swap( t, this );
